Not necessarily. I think you can workaround the issue by manually building the
overview on the .msk file as a post-processing step :
gdaladdo -ro --config COMPRESS_OVERVIEW DEFLATE small.tif.msk 2 4 8 16 32 64<font face="Times New Roman, Times, serif">

DEFLATE instead of JPEG as compression for overviews for the time
